Terpenoid-Based High-Performance Polyester with Tacticity-Independent Crystallinity and Chemical Circularity.

ABSTRACT: The development of chemically circular, bio-based polymers is an urgently needed solution to combat the plastic waste crisis. However, the most prominent, commercially implemented bio-based aliphatic polyester, poly(lactic acid) (PLA), is brittle, therefore largely limiting its broad applications. Herein, we introduce a class of aliphatic polyesters produced through the ring-opening polymerization (ROP) of (1R,5S)-8,8-dimethyl-3-oxabicyclo[3.2.1]octan-2-one (D-CamL) and the racemic mixture (rac-CamL), which exhibit superior materials properties relative to PLA. A metal-based or organic catalyst was used for the modulation of polymer tacticity. Notably, regardless of tacticity, poly(CamL) exhibits intrinsic crystallinity resulting in polyesters with high yield stress (24-39 MP
